Amazon Redshift launches RA3.large, a new smaller size in the RA3 node type with 2 vCPU and 16 GiB memory. You can now benefit from RA3.large as it gives more flexibility in compute options to choose from based on your workload requirements.
Amazon Redshift RA3.large offers all the innovation of Redshift Managed Storage (RMS), including scaling and paying for compute and storage independently, data sharing, write operations support for concurrency scaling, Zero-ETL, and Multi-AZ. Along with already available sizes in the RA3 node type, RA3.16xlarge, RA3.4xlarge and RA3.xlplus, now with the introduction of RA3.large, you have even more compute sizing options to choose from to address the diverse workload and price performance requirements.
To get started with RA3.large, you can create a cluster with the AWS Management Console or the create cluster API. To upgrade cluster from your Redshift DC2 environment to an RA3 cluster, you can take a snapshot of your existing cluster and restore it to an RA3 cluster, or do a resize from your existing cluster to a new RA3 cluster. To learn more about the RA3 node type, see the cluster management guide and the ’Upgrading to RA3 node type’ documentation. You can find more information on pricing by visiting the Amazon Redshift pricing page.
RA3.large is generally available in all commercial regions where the RA3 node type is available. For more details on regional availability, see the ’RA3 node type availability’ documentation.
